In glaucoma patients with anterior uveitis using brimonidine, one must consider `brimonidine-associated uveitis` to avoid misdiagnosis and over-treatment

Raised intraocular pressure (IOP) and secondary glaucoma due to underlying uveitis is a well-acknowledged phenomenon (1). The clinician should however keep in mind that topical IOP lowering medications can in themselves be a specific cause of uveitis (2). The alphaadrenergic drug brimonidine, is known to induce a type of anterior uveitis, the so called 'brimonidine-associated uveitis', which results in anterior chamber inflammation and further IOP increase (3).

In glaucoma patients using brimonidine, one must consider this phenomenon to avoid misdiagnosis and over-treatment with topical steroids, which in turn may increase IOP and induce other side-effects. Stopping brimonidine in these patients is usually sufficient for the resolution of anterior chamber inflammation (4).
